Tip
As previously noted, remember to add an Allow rule matching the SAT Multiplex rule.
Example 4.10. Multicast Forwarding - Address Translation
The following SAT Multiplex rule needs to be configured to match the scenario described above:
Web Interface
A. Create a custom service for multicast called multicast_service:
1. Go to Objects > Services > Add > TCP/UDP
2. Now enter:
• Name: multicast_service
• Type: UDP
• Destination: 1234
B. Create an IP rule:
1. Go to Rules > IP Rules > Add > IP Rule
2. Under General enter.
• Name: a name for the rule, for example Multicast_Multiplex
• Action: Multiplex SAT
• Service: multicast_service
3. Under Address Filter enter:
• Source Interface: wan
• Source Network: 192.168.10.1
• Destination Interface: core
• Destination Network: 239.192.10.0/24
4. Click the Multiplex SAT tab
5. Add interface if1 but leave the IPAddress empty
6. Add interface if2 but this time, enter 237.192.10.0 as the IPAddress
7. Make sure the Forwarded using IGMP checkbox is enabled
8. Click OK
Note: Replace Allow with NAT for source IP translation
If address translation of the source address is required, the Allow rule following the
SAT Multiplex rule should be replaced with a NAT rule.
4.6.3. IGMP Configuration
IGMP signalling between hosts and routers can be divided into two categories:
IGMP Reports
Reports are sent from hosts towards the router when a host wants to subscribe
